Transitions Theory for Intersections/Nodes and Generalized Euclidean Kinematics in Operation of Electrical Installations

In the operation of electrical installations risk assessment evaluates hazards and conflicts. A kinematics analogy for analyzing "collisions" risks offers a new approach for the operational procedures and the geometry and allows to introduce a transitions theory for intersections. The Euclid's fifth postulate can be assumed as criterion of certain collision and as definition of a generalized parallelism for avoiding collisions. For safety in electrical operation, the interactions with electrical equipment have to be promoted as contact and not collisions. The intersections of multiple traffic lanes present an analogy with the operation of nodes of electrical power systems, offering an equivalent experienced way for examining constraints in the transitions and suggesting new approaches and new methodologies for solutions. Euler Venn diagrams EVDs and transitions T-maps have been introduced for assisting the design of operational procedures and the training of operators. A 3D approach for EVDs ant T-maps can help guarantee safety and avoid collisions.
